Hillsboro-based Advanced Inquiry Systems Inc. reports in a securities filing today that it's raised $10 million of a new, $14.5 million funding round.

AISI, formerly Octavian Scientific, raised $11 million last year when it completed its second funding round. It's now attracted $43 million altogether.

The five-year-old company was initially backed by OVP Venture Partners, TL Ventures, Intel Capital, Applied Ventures, KT
Ventures and Northwest Ventures. All those backers joined the second-round investment.

Today's filing did not say who provided the new funds to AISI, which has been developing new technology to test semiconductors. The company could not be immediately reached for comment.

AISI had 22 employees when it closed its last funding round 11 months ago. At the time, AISI said it had just received an order from a large memory chip manufacturer in Asia.
